Question
Is it hard to swap my98 2.2 engine over for a 4.3 v6 from a 91 Chevy blazer and still be good with smiting and would it be easy

Answer
HI LONNELL,THIS WILL BE A HARD AND WILL TAKE ALOT OF TIME TO DO SO..WILL NEED TO REPLACE MANY PARTS..FUEL PUMP,WIRING HARNESSES,PCM AND ON AND ON. NOTHING WILL WORK.NOTHING WILL TALK TO EACH OTHER. I WOULD SUGGEST REPLACING THE ENGINE WITH THE SAME SIZE AND YEAR ENGINE..HOPE THIS HELPS YOU..TOM
